Tire tread



FIG. 1 is a perspective view of a tire tread showing my new design, it being understood that the tread pattern is repeated uniformly throughout the circumference of the tire;

FIG. 2 is a front elevational view thereof; and,

FIG. 3 is a side elevational view thereof on a reduced scale.

The broken line showing of the tire sidewall in the drawings is for illustrative purposes only and forms no part of the claimed design. 

The ornamental design for a tire tread, as shown and described.
